| description | A submarine cable with optical fibers which prevents damage to the fibers due to water pressure without the use of an external armor. The cable has a central core with a strand which provides the cable tensile strength and which is surrounded and contacted by a layer of plastic material which has helical grooves which receive the optical fibers which may have a protective covering. The layer of plastic material is surrounded by sheath in the form of a layer of plastic material. The grooves and any spaces radially inwardly of the sheath, such as the spaces between the wires of the strands, are filled with a substantially incompressible fluid, such as a grease or jelly. If the optical fiber protective layer is a tube loosely receiving the optical fiber, or optical fibers, the space within the tube not filled by optical fibers is filled with a substantially incompressible fluid. The layer of plastic material forming the sheath may at least partially extend into the grooves. |
